cds-question@unistra.frgalaxiesinfrared-photometryultraviolet-photometryradio-sourcesWe address the relation between star formation and active galactic nucleus (AGN) activity in a sample of 231 nearby (0.0002<z<0.0358) early-type galaxies by carrying out a multi-wavelength study using archival observations in the UV, IR, and radio. Our results indicate that early-type galaxies in the current epoch are rarely powerful AGNs, with P<10^22^W/Hz for a majority of the galaxies. Only massive galaxies are capable of hosting powerful radio sources while less massive galaxies are hosts to lower radio power sources. Evidence of ongoing star formation is seen in approximately 7% of the sample. The star formation rate (SFR) of these galaxies is less than 0.1M_{sun}_/yr. They also tend to be radio faint (P<10^22^W/Hz). There is a nearly equal fraction of star-forming galaxies in radio faint (P<10^22^W/Hz) and radio bright galaxies (P>=10^22^W/Hz) suggesting that both star formation and radio mode feedback are constrained to be very low in our sample. We notice that our galaxy sample and the Brightest Cluster Galaxies follow similar trends in radio power versus SFR. This may be produced if both radio power and SFR are related to stellar mass.2016ApJ...818..182Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/818/182CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/92 : The FIRST Survey Catalog, Version 2014Dec17 (Helfand+ 2015)II/328 : AllWISE Data Release (Cutri+ 2013)II/312 : GALEX-DR5 (GR5) sources from AIS and MIS (Bianchi+ 2011)VIII/81 : Sydney University Molonglo Sky Survey (SUMSS V2.1) (Mauch+ 2008)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)J/MNRAS/446/2985 : Double-lobed radio sources catalog (van Velzen+, 2015)J/MNRAS/444/L63 : SFRs of Brightest Cluster Galaxies (Fraser-McKelvie+, 2014)J/AJ/146/46 : Star Formation Rate in nearby galaxies (Karachentsev+, 2013)J/MNRAS/423/422 : Early-type BCGs with star formation (Liu+, 2012)J/ApJ/731/L41 : 1.4GHz obs. of bright early-type galaxies (Brown+, 2011)J/ApJ/706/599 : H{alpha} and UV SFR in the local volume (Lee+, 2009)J/ApJS/176/39 : IR survey of brightest cluster galaxies I.
